Nothing transforms an LS like boost. Sam's Performance fits and tunes Harrop superchargers on everything from stock Commodores to forged strokers, and every one leaves wearing the plate that says "Harrop enhanced by Sam's Performance".

For naturally aspirated LS2 and LS3 cars, a Harrop supercharger is the biggest single step up in performance. We fit the Harrop 2300 and the larger 2650, matched with our own blower camshaft, lifter and valve spring packages and a full exhaust, then tune the whole package on our hub dyno.
Results speak for themselves: a VE SS with a Harrop 2300 made 620+ rwhp, a VE GTS LS2 with a Harrop blower and our cam and lifter package made 620+ rwhp, and a VF SS with a Harrop 2650 and our cam package made over 700 rwhp.
HSV GTS, GTSR, Clubsport and Maloo owners with the factory supercharged LSA can unlock a lot more with Harrop boosted pulleys and airbox, our cam package and a full Hurricane exhaust. Our VF GTS and GTSR Maloo builds in this spec made 650+ rwhp, and a VF GTS with our heads and cam package made 750 rwhp on E85.
Sam has a long history with the LSA. Back in 2015 he told Street Machine the workshop had already done "probably over 100 cars".
It is not all Holden. We fit Tickford Roush supercharger kits too: an S650 Mustang GT left our workshop making just under 600 hp at the wheels. Call us about your platform.

It depends on the supporting parts. At Sam's Performance, a VF SS with a Harrop 2650 supercharger and Sam's cam package made over 700 rwhp, and a VE SS with a Harrop 2300 made 620+ rwhp. A stock-bottom-end combination is tuned to suit the engine's limits.
Both are Harrop superchargers for LS engines. The 2650 is the larger unit and suits larger-capacity strokers and higher power targets. Sam's Performance has used the 2300 on a 402ci stroker for over 700 rwhp and the 2650 on a 416ci stroker for 800+ rwhp.
Yes. Sam's Performance fits Harrop boosted pulleys and airbox, its own cam and lifter packages, ported heads and full Hurricane exhausts to LSA-powered HSVs. Builds in this style have made 640 to 750 rwhp, the top figure on E85.
